Study And Realization Of Rail-track Engineering GIS Based On Web Technique

The research and realization of "rail-track engineering GIS based on Web technique" is the principal content. In the environment of Internet, taking IIS module of windows as Webserver, and taking MapXtreme, the product of Mapinfo Inc as MapServer, the article emphatically expatiates the constructing project of rail-track engineering based on B/S; detailedly designs the rail-track engineering database with the character of rail-track engineering data. Based on the above research, the article discusses the process using ASP and ADO technique to manage and update database; studies the setting of purview to assure the security of system; discusses the function of layercontrol, eagle-eye navigation, search of information and etc.; discusses the function of statistic and analysis by the process doing the caky statistic chart of roadbed disease; analyzes the doing of distributing special map of disease and engineering with the character of rail-track engineering GIS.The foundation of system has high value of reference to the building of entire rail-track engineering GIS.
